Agile Cirlce1

In continuation of my previous questions blog [https://vskumar.blog/2017/09/04/sdlc-agile-interview-questions-for-freshers-1] on this topic these were made.

SDLC and Agile Model:

Questions on SDLC Phases:

1. How the agile methodology has been architected?

Ans: The agile methodology has been architected with 12 principles to govern the agile development approach.

2. What is highest priority during agile development model?

Ans: The highest priority is customer satisfaction and the early and continuous delivery of software which will work for the customer requirement.

3. Why the agile development models need to accept the request on irrespective of the development stage?

Ans: As per the  fundamental approach of agile development  it provides facility to the users towards inception of new or enhanced requirements before the delivery.

4. During agile development approach who all need to work together?

Ans: The business people and software developers need to work collaboratively and consistently throughout the project life cycle.

5. To get the right delivery what do we need to do during agile development model?

Ans: In agile project we need to have self motivated individuals at the same time we also need to supply the required human and nonhuman resources to get the job done.

6. When the life cycle of agile model ends?

Ans: The agile model continues till the retirement of the product or project. When the customer decides the retirement of the product then the project operation is terminated. 

7. Why do we need to have face to face conversation during agile development approach?

Ans: The agile principle guides to have face to face conversation among the project resources to have most efficient and effective method of communication.

8. How can you measure the progress and success of agile project?

Ans: The basic concept of agile is to deliver the working software of component.

9. How  the agile development process need to be promoted and to whom  all ?

Ans: Agile development process need to be promoted in a  sustainable development for continuous delivery to the sponsors, developers and users.

10. Why do we need technical excellence and good design project delivery?

Ans: The concept of the agile is for continuous delivery to the users as per the requirements in an iterative development approach. The team capacity needs to be accelerated towards the functions and processes to work on good software design.

SDLC & Agile – Interview questions for Freshers -1

Agile Cirlce1

If you are a fresher for an IT  job trials this might be useful.

Please note as per the current global IT Industry trend most of the IT organizations have moved into Agile SDLC  and Continuous delivery cycles. Hence you, being fresher should be ready with this knowledge. I have made some of the below questions related to this topic.

[Also look into my old blog: https://vskumar.blog/2016/11/24/on-job-training-for-future-software-engineers-freshers-how-it-saves-their-career-time/]

SDLC AND Agile Model:

Questions on SDLC Phases:

1. What are the general phases for SDLC [Software Development Life Cycle] ?

Ans: In any development model  [SDLC] following are the different phases for software delivery : 

a) Requirements Investigation and analyzing

b) Design

c) Development

d) Implementation

e) Management

2. Where can you get requirement specifications in SDLC?

Ans: During the phase of Requirement investigation and analysis, the output will be Software Requirement Specifications. In every project during this phase user involvement is essential to get the business requirements to make the right software.

3. What is the procedure to derive the design specification?

Ans: During design phase the design specifications will be output of this activity. During this phase the final SRS is considered and it should be derived for design specification against each requirement. One requirement can have more than one design specifications. Basically you will be decomposed the software requirement into one or more design specification(s).

4. What is development or construction?

Ans: Once the design specifications have been baselined, the developer takes the design specifications to convert them into code. This activity is called constructing or developing code. The technology should be used for coding need to be  specified in the design documentation. Example: Let us assume you want to develop the code in Java, so the technology should be Java.

5. What is implementation in SDLC?

Ans: The implementation activity need to be started once the code construction is completed, the code construction involves coding, code review and unit testing, integration testing. Once these 3 tasks are completed the project is moved to next phase that is implementation. During implementation phase the relevant test environment is considered for deployment of software builds for test cycles. Depends on the SDLC model;  system testing and user acceptance testing can be performed, during the implementation software build can be deployed into live  once the user certify UAT [User Acceptance Testing]. The Live environment is also called production environment.

 

6. What is the meaning for  software management and retirement?

Ans: Once the software is deployed into production or live environment under first release there can be bug fixes  or software enhancements; those can occur under application management life cycle and which can be a software management also. With this concept software is being upgraded during its life time. When the new technology or business systems are considered towards   equivalent or more of the current software features then current software build should  be retired.

Example: A mainframe [COBOL/DB2/CICS] application can be converted into windows based with Java technology. Then the existing COBOL/DB2/CICS application can be planned for a retirement with the replacement of the newly planned application. The new application can also have some more software features or the same features can be implemented.

Questions on Agile:

7. How the agile development model pulls the ideas ?

Ans: Agile development model pulls the ideas in a phased manner in the following way, by using a) Prototyping   b) iterative development c) Rapid prototyping. During these phases the stakeholders or users involvement is mandatory. Their needs or suggestions also comes into the ideas for making the right software.

8. How the agile model champions the ideas?

Ans: By following various phases, different ideas are generated into the agile model. Using this approach it accelerates  the software engineering team to get the right results through different software delivery iterations.

9. Why traditional approach of SDLC is not suitable for agile development model?

Ans: During the traditional approach we do not have prototyping and iterative development in the SDLC. Using the prototyping the demo can be conducted on a conceptual model of the [new or existing] software. Then the  users can visualize these thoughts to extend the demo version into their live software. Then iterations comes into picture as  part by part to deliver  the working software in the agile development model.

To give you with some  more clarity;  Agile development model involves continuous construction and delivery using the phases of prototyping and iterative. For each iteration there can be prototype demonstration. Once the demo is approved the iteration will start for construction and implementation. In traditional model if we want to use for prototyping there is a phased prototype model and rapid prototype model are used, once they are approved by users the project team need to choose one of the traditional model SDLC. In this case there are two parts of delivery need to be considered where as in an agile model they are in-built for fast planning and iteration.

10. During agile model what kind of teams need to be formed to initiate the project?

Ans: To work in the agile development project we need the teams in small size, highly talented and responsive people.

11. During agile model how software requirements  are considered for delivery?

Ans: Agile team needs to consider the essential,  prioritized and deliverable requirements [within cycle time] from the users and construct the software in small increments those are called SPRINTS for delivery.

How to Reduce Agile cycle time with reusable code ? [with Video lessons] # Kindle

Agile practices and the importance of Re-usable code libraries for cycle time reductionReusable code usage for Agile iterations planning by examples:

In many Agile transformation sessions the Agile practitioners or savvy’s discuss more on the process related activities rather than elaborating on the technical or software engineering process steps to reduce the cycle time.

At the same time prior to the Agile meetings, activity efforts need to be defined by the designers and the developers. Unless they identify the size of the reusable code components in the applications it is not worth for conducting the Release or Sprint planning meetings for planning of the iterations.

Hence it is the moral responsibility of the technical teams to apply this kind of practices ahead of Agile process or Scrum meetings.

If you are interested to know what reusable code with examples is, this E-Book can be useful. Using this technique, you can plan for code refractor and its cleaning also to get ROI on future Agile iterations. During Scrum meetings, these are the important topics where technical people need to discuss for customer’s ROI acceleration planning and also the cycle time reduction acceleration. The team’s technical capabilities also can be accelerated by following these practices regularly.

I have considered an application example of E-commerce site building for defining the Sprint planning and their iterations. Each iteration has been divided into different reusable code components design parts.

The relevant graphics have been designed and added into this E-book. The software configuration processes with Code Items process have been discussed also.

One can answer the following after understanding this E-Book content:
How to define the reusable code?
How the Iterations can be planned?
Is it possible to demonstrate the iterations cycle time reduction?
What are the entry criteria for Sprint planning?
What are the jumpstart activities required for designers before Agile release meeting?
How to manage the code components with configuration management process?
How to plan the efforts reduction for Sprint cycles?

The proposed or mandatory readers are:
Agile developers
Agile Designers
Agile PMS
Agile Product Owners
Agile teams
Who all intended to learn Agile Practices?
